In the resent extensive use of hydraulic concrete or sidewalks and curbing the provision of some efficient protector of the face and corner of the curb from accidental injury and'from shock and abrasion by the wheels of vehicles .becomes important. Various forms of protectors have been devised, most of them comprising a metal facing with means of anchoring the facing or protector in place. The most common form consists of a wrought iron or,cast iron bar or rail having a cross section similar to that known as a T shape, the stem of which projects into the body of the concrete, the adhesion be tween this stem and the concrete being depended upon to resist the detachment of the protector Some of these devices have this stem provided with openings or projecting lugs or pins for better engagement with the concrete, but even when rovided with these aids, the anchorage of t e protector in the concrete is often insufficient to hold it firmly in place. Moreover, it is found in. practice that when the protector is made of cast iron, the unequal rate of cooling and consequent unequal contraction of the head and the stem of such a section causes it to assume a 'bent or distorted form; and ifthe protector ,makes it difficult to properly tamp the concrete under and around it, or to do this with out disturbing the position of the protector.

The object of m invention is to produce acurb protector w ich shall not only furnish a more secure anchorage in the concrete, but shall overcome or avoid the defects and diilicultiea' pointed out, and shall. at the same time be more easilyplaced in' position and less expensive than protectors heretofore devised. In accordance with the invention the face plate is formed without a broad flange or stem and the anchoring device consists of a wire or rod or a flat strip of metal bent to form suitable loops, permanently secured to the faceplate at intervals.

The invention will be more fully described hereinafter with reference to the accompany: ing drawings in which it is illustrated and in which;

Figure l is a view in vertical transverse section of a concrete curb with one form of the improved protector in place. Fig. 2 is a plan view of a portion of the improved protector. Fig. 3 is a view of the inner side of the face plate, a portion of the anchoring device being shown. Figv l is a view in transverse section of the face plate without the anchoring device. Fig. 5 1s a view similar to Fig. 4: but showing a variation in form. Figs. 6 and 7 areviews in transverse section and in plan of a cast face plate with its anchoring device.

The improved protector consists of a face late or member a and ananchoring member The fare plate or member a, as shown in Figs. l-5, is preferably rolled, having a suitable profile and capable of being bent or curved either at the factory or on the street whereused to conform to the desired line of the curbing. It is rolled with a lip or lips c on its face, and is produced in lengths convenient for handling, say from five to ten feet long. The anchoring memher 5 is a rod or wire or strip of'flat metal which is bent to form open loops of suitable shape, as shown in Fig. 2, and to be permanently engaged with the face plate or member at intervals between the loops by pinch-- or bending the lip or lips 0 upon it, as shown in Figs. 1, 2 and 3. Preferably each section of the protector is completed at the factory, being sent out straight for all well-- nary work or specially formed. to suit curves of short radius. The straight sections can be sent easily on the job to conform to de- PPUT'fLlI'QS of the curb from a straight line, the loops of the anchoring member being distor" of the face member.

in the construction of the curb the-protcctor set in its proper position, the face plate resting against the form used for shaping the face of the curb, where it is ed readily to accommodate the bending the wire secured by suitable clamping devices, and the concrete is then shoveled into place. The form and section of the anchoring iece offers little resistance to the placing 0 the concrete, which readily falls or flows around it, and" the concrete may, with reasonable care, be properly tamped in the usual manner without disturbing the rotector. It will-be observed, moreover, t at the form and character of the anchoring device employed secures effective contact with the concrete and maximum resistance to the dis lacement or movement of the rotector. 7 he improved protector is capab c of being produced by casting if a cast protector is preferred. As shown in Figs. 6 and 7 the anchoring wire b is secured to the face member a by casting the latter about the adjacent portions of the loops of the wire I), as at c. In this construction no lips are formed on the inner face of the face member, but only the projections c which are cast about It will be understood that various changes in details of form and construction can be made to suit diflerent conditions of use without departing from thespiritjof 'the invention.

I claim asny invention,

1. A concrete curb protector comprising a metal face plate and a continuous rod or wire anchoring member bent to form 0 en plate at intervals between-the loops. r

2. A concrete curb rotector comprising a metal face plate provided with a lip' on its inner. face and a continuous rod or wire anchoring member bent to formopen loo s and permanentlyengaged at intervals by t e lip of the faceplate between the loops.
